Dai Qiang, for what do you need that data? I can only think of animating the model. This works already for the gear model. And an reasonable animation of the wings could be easily faked. All you need is the amount of lift they produce. Divide that with a constant weight-force of the plane (e.g. MTOW * earth acceleration) and you get a number that is zero when the wings produce no lift and 1 during a steady flight (and somewhere above 7 when the wings break...)
